Froth flotation Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The development of froth flotation has improved the recovery of valuable minerals, such as copper- and le

Froth Flotation of Iron Ores sapub

The practice of froth washing in direct flotation increases concentrate grades without significant recovery losses[59]. In the reverse flotation of iron ores, froth washing was found effective in reducing the loss of FINE iron oxide particles to froth. It was reported that the cost of installing a column flotation circuit is approximately 25%

Froth Flotation Method JXSC Machine

The froth flotation method is widely used to treat various veins of gold and silver ores for the following reasons: (1) In most cases, the froth flotation process can enrich gold and silver in sulfide concentrate to the greatest extent and discard a large number of tailings, thus reducing the smelting cost.
